Application filed 'Jnly 18,

vThis invention relates to machines of the type that are l'employed.'l'or rolling threads on boltfblanks', although certain' et thejfea?Vtures embodied herein may well be capable of usein machines used forothersecitic purposes. Therefore, while my invention is shown asapplicable to, and actually: eniployediin connection with, a'machine'o'fthe] type referred to, it is not intended thereby to limit theimprovements set forth her-matter only to a. machine of such'particulartype. l

In machiiiesthat have lbeen employed tor the specific purposementioned,k it has been proposed to deliver the headed bolt-blanks.automatically from a'chuteto and between aA fixed die and a movable die,winch cooperate to rollthreads 1pon the Shanks otsaeh blanks and therebyto complete thebots. However,

euchantomat-ic feeding mech anisms have'not' been generally satisfactoryand, on that ac' count, the blanks are usually deliveredv manoperatethereon; also to provide anelticient construction of chute for4delivering articles therefrom to such dies or mecl'ianism.

A furtherdisadvantage'which has attended theuse ot lixedand movaole diesfor rolling threads on articles such as boltfblanls has been the failureof the'bolts orart'i'cles tobe.

discharged from the dies' afterthethreads hmy ',beennrolled thereon,causing abolt or artA ie so treated to bebroughtlbacl, with the movabledie, into Contact with other'parts" ol the mechanism, causinginjurythereto.

It is the turther Igeneral object oft my invention to provide, formachines of the general character described, means whereby,.should abolt or like article be so broughtback by the movable die, the operationot the.l ieedinig'` nieclmnisinwill be automatically suspended,

' and the article thus brought back may be'icon-V veniently removedwithout injury yto the nie-cham'sin.V` l n y A Further and more limitedobjects of. the invention rwill appear hereinafter, and ,all

The mechanism vfor feeding thelblanks is carried by i vbase plate B havinga machined seat Bat one endthereof and provided with horizontally' spaced lugsr Btojwhiehjthe loweryends of parallel-,rulelinli's yare pivoted,

the upper 'ends of the links beingv j iy'otedv the 'base of aVtrame-casting C. j These links are `preferably made in pairs,eachpair'being connected across brace B* (see Fig.' This frame-casting'.is provided witha maj-gV Vtion and a three-part lower section.

chined foot C' whichis adapted to rest upon the seat B.

For convenienceV of description, the leftk is a vertical chute,indicated generally at D.

This chute receives the headed blanksV or shanls, one at a time, from adownwardly and rearwardly inclined chute, indicated generally at E, anddelivers them one at a time, to and between the dies A2, A3.

The vertical chute D will now be described in detail. Y

The chute comprises a two-part upper sec- The inner wall of the uppersection D (see Figs.

6 and 8) is rounded, except for the front end thereof into which therear end of the chute E projects, and the bore thus formed diminishesgradually in cross sectional area from the to-p to the bottom thereof.'.Pivotedto the front of the part D and cooperatingtherewith to formtheupper partfofthe chute, is a gate F, the pivotal support whereof isindicated at F. This gate is provided with a slot in the front thereofto accommodate certain delivery portions of the chute E and has securedto the lower portion thereof a blocliF2having an inverted truste-conicalsurface F3 and a cylindrical surface F4 therebelow. The gate is normallyheld closed by means of a spring F5 secured at one end' to one side.thereof and at its other end to a iixed point on the side of the chuteD.

lVithin the upper portion of the bore of the chute section D is a guideplate, indicated generally at G. This plate has an upper flange Gf bywhich it is fastened to the top of the rear of the chute, being providedbelow such flange with a downwardly and forwardly inclined portion G2from which the Y plate extends rearwardly and downwardly,

as shown at G2'. The purpose of this plate will be explained hereinafterin connection with the details of the chute E.

The lower portion ofthe chute D comprises` a ffixed rear member D2havinglateral reeral type. The front members D5 of the lower portion'of thechute D are normally held in the positions shown in the drawings bymeans of plungers D7 mounted inthe lower fixed section D2 et the chuteand pressed into engagement with the arms D6 by springs D8 (see Fig.102). The arrangement of the pusher bar H with referenceto the fixed andmovable dies A2 and A3 is shown in Fig. 11.

The chute E is shown as composed of a pair of channeled plates securedtogether in space-d relation, with their lianges E presented outwardly,forming therebetween a downwardly inclined passageway E2 for thebolt-blanks. Secured to each upper llange is a wear plate E3 on whichthe heads of the bolt-blanks are adapted to rest as the blanks slidedown the inclined chut-e E. In order to secure the channels of the chuteE in spaced relation, one or more straps E4 may be secured tothe bottomflanges of t-he said channels, the bottoms of the said straps beingshown as bent downwardly, to permit the passage of a long bolt-blankthereabove. The channeled plates E constitute side plates for theinclined chute and each of these plates is thickened and widened at itslower end by means of a thick plate E5 bolted thereto, each of saidplates E5 having a downwardly and forwardly inclined shoulder' E adaptedto engage a similar inclined surface D9 on one of the side members ofthe chuteD. From this shoulder, each of the plates E5 projects into thefront of the upper chute section and is provided with a downwardly andforwardly inclined front edge ET engaging a correspondingly shaped seatD10 in said chute section (see Figs. l and 6).

To facilitate the proper delivery of the blanks from the .chute E2 intothe vertical chute D, the passage for the shanks at the lower ordelivery end ol the chute is contracted to approximately the diametersof the Shanks by means liner plates E2. These liner plates may be madeof several sections, as indicated, the rearmost sections having theirinner faces converging rearwardly. The inner ends of the liner platesproject into the bore of the vertical part D of the chute D, with theirinner or rear ends beveled outwardly, as shown at E2, and such beveledends also extending downwardly and rear-4 wardly toward the rear wall ofthe chute section D (see 6 and 8). The purpose of the plate G and theparticular construction et the inner ends of the sides et the chuteLeest-1e.

E, as constituted by the rear ends of' the plates E8, is to prevent thebolt-blanks vdelivereclinto the chiite D1 from" becoinfing inverted inor lodging across the said chute. The blanks dislodged from the'inclined chute are apt to rebound in'thevertical chute and tei-becomertwisted or turned therein in such manner aste prevent them from beingdelivered freely, with their headsY up, down the chute D. B y theconstruction shown herein, theV head' ofa bolt-blank delivered from thechute E will strike the inclined surface G2', and the shank of the blankwill swing into engagement with the surface* Ge; the head olfv the blankrebounds from such surface G2- and strikes the downwardly and rearwardlyinclined edges E* of the plates E8, and the blank will be prevented bysuch plates andthe rear wall of the upperpart of the ehu-te D frombeingA turned to' such a position 'as to cause it to'obstrue-t the saidchute;y In the event that the head of lthe bolt-blank should be thrownforwardly, after passing the surface E?, it will strike the downwardlyinclined surface'F, thereby causing/the blank to beV straightened upbeforereaching the bottom of the lower part of thechute.

The side members of the chute E are pro- Y vided, near their lowerendswith slots E1",

E and E for the reception ofthe automatically operated arms fordelivering the blanks one ata time, and at the proper time, from theinclined chute to the vertical'chute; The construction` and mode'ofoperation of the' automatic bolt-feeding mechanism will now bedescribed. v l

Bolted to a flange at the top of the'fr'amecasting C is a bracket Jcarrying a journal j sleeved in which is mounted a shaft The shaftprojects ,forwardly beyond the end `of the journal sleeved and hassecured to its upper end a curved :arm K the lowlnerend of which isadapted, by the rockingof the shaft K, to be projected throughandwithdrawn from the alined slots El inthechanneled side members of thechute E, thereby serving, when in the space between said channeledplates, to hold the bolt-blanks thereabove against downward movementand, when withdrawn, to permit the said blanks to move downwardly.Secured to the same shaft K is a `curved arm K2 which extends from theopposite side of said yshaft and is adapted to be projected into andwithdrawn from vthe slots E thereby to prevent the lower most boltblankthe chute E 'from being delivered into the chute D until' ther arm iswithdrawn from the slots E, The arms K and K* Yare so arranged that oneof these two arms will be projected across the inclined chute whenwthe,other is withdrawn, and vice versa; ,and the space between the slots Enand E is substantially e ual tothe .diameter ,of thefshank `ef a .bolt-1211111- A Spa-Cingwasher J f is interposed between the ends et the armsK" and K2 which are keyed upon theA shatt'K. To facilitate the properdeliveryv into the 'chute D ofthe lowermost bolt-blank from its positionbetweenthe slots E10 and E, the arm K has secured thereto a. cur-ved armKev thelowery end of which is adapted to be projected into and throughthe slots "Ell2 when theiarm K is inserted into and through the slotsEl. thereabove. The lower vend ofthe arm K? is beveled, as shown at K4,

being retained upon the shaft by means, of. The clutch collar K5 has anotchI nuts K8. n on each side of the upper end thereoi` and providedwith a forwardly and downwardly beveled surface K. Loosely mounted uponthev shaft K above'theclutch collar'K5 is a sleeve L, the said sleevehaving two arms L and L2 projecting therefrom. A spring M is connectedat oneend .to the arm L and at its-opposite end' to the frame-casting C.The arniL2 isprovided with the socket L3 of a ball-and-socket joint, theball L4 being cal'- ried ,by the upper end of ailongitudinally-`extensible-andicontractible link L5, thelower end of which is providedwith aA ball L6 which is seated within a socket N 'in the upperintermediate par-t ,of va lever N, which lever has a downwardlyand'forwardly extending end N2 provided with a roller N3,`f0r a purposetobe described hereinafter. The 'rear end of the lever N is mounted ona'stud shaft NL (see Fig. 9), which is supported by a journal sleevebolted to the framecasting C and carrying ajournal N6 for a shaft towhich is rigidly secured an arm Of having at its lower and *forward enda rollerA O2. i

vProjecting from the shaft O land. rigid therewith is an arm O, whicharm is' forked at its upper end, to receive therewithin a cross member Pon a sliding gate P which is adapted tolbe reciprocated across the boreof the chute D, being provided with an arcuate slot PZ'in the front endthereof (see Figs. 1,3 and 9). The end of the shaft O which is voppositethe arm O is supported by a block ,O4 .carried by a' part 'of theframe-casting-VC. Secured to 'the end of the shaft O beyond block O isan ,arm G, which'a-rm has secured thereto one end of a spring O, theopposite end of the spring being secured to an arm` O7' carried by thechute D.l

Y A,Connected to and n'iovab'le with the die A3 is a cani slide R, thesaid .slide 'having an upper elevated track. R vand a 'lower delaopressed track R2 connected by an inclined track The rollers l 3 and O2are adapted to ride upon this track, `normally being held in engagementtherewith by the springs M and O3, respectively.

t Secured to and projecting rearwardly from the rearV pair'of links B3is an arm SV from the rear end of which is suspended a counterweight S',the counterweight being such that, if the mechanism supported by the`framecasting C in front thereof be moved a short distance rearwardly,the counter-weight willy l and 10, wherein the arm K2 blocks thedelivery of the bolts to the chute D therebelow, the arm Kbeingwithdrawn from the slots E11 and the arm K3 from the slots. K12.

The slide R will be moved rearwardly until the roller N3 rides off theupper track R onto the lower track R2. This enables the spring M to rockthe vshaft K, through the clutch members L and 'K2-withdrawing the armAK2 and simultaneously inserting the arms K and K3 across the chute D.The arm K will hold the stack of bolt-blanks thereabove from movingdownwardly along the guide constituted by the chute E, but the arm K2,being withdrawn, will allow the lowermost bolt-blank to slide down'intothe chute D, the movement of said bolt being accelerated by the beveledend of the arm K3. The bolt-blank so discharged will be delivered withits lower end resting on top ofthe slide P which meanwhile has beenmoved forwardly by the action ofthe spring O3 Vand arms O3V and O5 whenthe roller O2 rides olf the track R 'ontothe lower track R2. o

Onv the reverse movement of the slide R, the rollers N3 and O2 ride uponthe upper track R. The roller N3 elevates the arm N and, the arm Ls an drocks the shaft K through the `clutch members L and K5, thereby7withdrawingthe arms K and K3 from the chute l) and att-he same timeinserting the arm K2 therein. This will enable the stack of boltblanksto move one ste-p downwardly, with the lowermost bolt-blank held in thelowermost position inthe chute E by the arm K2. While this action istaking place,.the roller O3 will have been lifted, rocking the shaft Oand moving the slide P rearwardly, thereby permitting the bolt-blankthat was resting thereon to drop into the lower portion of the verticalchute, with. Aits head in the tapered lowerfend of the chute.` When thebolt is in this position, the movable die A3 and the fixed die A2 are inapproximately the positions 'shown in Fig. 11, wherein the end H2 of thepusher bar is about to engage the bolt--vv blank and push it-upontherearvend ofthe fixed die so as to insure the proper grip-ping of theblank between the fixed and movable. dies. The parts are 'soarrangedthat the roll-` er H will engage the front crossed ends of with theswinging gatetF, discharging the blank through the front opening in thechute.

As pointed out hereinbefore, it happens sometimes that a boltblankinserted between the fixed and movable dies is not disengaged anddelivered therefrom at the end of the forward thread-rollingmovement ofthe movable die. vWhen this occurs, such a bolt will be carriedrearwardly by the movable die into engagement with the mechanism,thereby endangering the latter. -To prevent injury to the mechanism bysuch action ,the said mechanism is supported from the-base A on thelinks B3.` Should a bolt be carried rearwardly andstrikethe lowerportionof, the vertical chute, the impact ofithe boltwill cause theframe-casting C and the parts attached to be moved upwardly7 andrearwardly, this action being facilitated by. thecounterweight S.. Thiswill result in lifting the rollers O? and N3 above the upper track R andwill prevent the operation ofy the bolt-feeding and deliveringmechanismuntil such time as the defective bolt shall havebeen removedandtheparts restored-tothe normal working position indicated in Fig. 1.y

Should the movement of any of the arms K', K2, orfK3across the chuteEbe'opposed unduly, as by encountering a blank which is hung upv in thechute, this opposition to or stoppage of the movement of such arm willcause the clutch sleeve K5 to be moved rearwardly by the engagement ofthe appropriate projection LT on the` sleeve L wit-h its correspondinginclined surface K, thus breaking the driving connection between sucharm` and the shaft K and' preventing injury to the mechanism fordelivering the bolt-blanks to the chute D.. .f a I As is well known tothose skilledin the `art to which this invention relates. t-he movabledie A3 and the pusherbar willr be operated from al common shaft. as bymeans of cranks.
